Enhanced Datasource 0MATERIAL_ATTR

Hi all,

I have enhanced datasource 0MATERIAL_ATTR with a few ZZ-fields that the customer needs.

Now the customer <b>changed the datatype of one of these ZZ-Fields from NUMC 5 to CHAR 4.</b>

Do I have to <b>recreate my datasource for 0MATERIAL_ATTR</b> now, which means <b>deleting my existing Append Structure ZABIW_MARA_S and start from scratch</b> or can I <b>make the changes in the existing APPEND Structure</b>?

<b>How do I do that then?</b>

Thanks

Christian
